Growth analysis of potato using a satellite image and GIS

[ABSTRACT] Site-specific crop management requires the evaluation map of crop conditions, yields and crop quality. In Hokkaido, evaluation maps of rice and wheat were created and used effectively for precision farming. To continue with this trend of research, the current study focuses on producing potatoes. Then for developing the map of potato, the analysis of the growth was conducted in the Memuro town, Hokkaido. The equations to estimate root yields and starch concentration of potatoes were derived from Quick Bird satellite image acquired on July 18, 2004, and the spatial distribution maps were created through these equations. The result indicated that root yield and starch concentration were affected by species of preceding crop. The fields with the highest root yields were detected in the fields where the sugar beets were cultivated in the previous year, and the average yield was 37.4t/ha.
